Caesar Wang e4c8cd82d5 soc: rockchip: power-domain: avoid infinite loop ... In some cases, we have met the infinite loop in rockchip_pmu_set_idle_request() or rockchip_do_pmu_set_power_domain(). As the crosbug.com/p/57351 reported, the boot hangs right after this [1.629163] bootconsole [uart8250] disabled [1.639286] [drm:drm_core_init] Initialized drm 1.1.0 20060810 [1.645926] [drm:drm_get_platform_dev] Initialized vgem 1.0.0 20120112.. [1.654558] iommu: Adding device ff8f0000.vop to group 0 [1.660569] iommu: Adding device ff900000.vop to group 1 <hang> This patch adds the error message and timeout to avoid infinite loop if it fails to get the ack.
